What data for this category looks like
The data for this category mainly comes from product digital models and GD&T specifications, process route documents, coordinate measuring machine data, on-site trial feedback, and metrology systems. Daily documents include tooling requirement documents, positioning datum schemes, fixture drawings, gauge operation manuals, acceptance reports, calibration records, and change histories. Data updates follow project progress, product changes, or regular calibration cycles. Fields include positioning datum parameters, tolerance values, calibration cycles, change version numbers, and other relevant details. Common units are millimeters, microns, and days.
Constraints for HTTP interfaces and external systems
Data sources for this category are scattered and have diverse structures. HTTP interfaces must support receiving structured process parameters, measurement data, and all types of document attachments. Data updates have no fixed cycle. Interfaces must adapt to synchronization triggers initiated by projects, product changes, or calibration milestones. Data fields include specialized parameters such as positioning datums and tolerance values. Interfaces must have clear field mapping rules to match business formats. Since errors directly impact production quality, interfaces must include basic validation and failure retry mechanisms to ensure accurate data transmission.
Configuration settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Authentication string carrying a Bearer Token | Matches the interface authentication requirements of external systems, ensures access security, and complies with FastGPT v4.17.0 interface specifications |
| Timeout period | 600–1200 seconds | Adapts to the processing duration of batch synchronization for multiple documents, prevents mid-transfer interruptions |
| Chunk length | 800–1200 characters | Matches the content density of documents such as fixture drawings and calibration records, ensures semantic integrity |
responseData | Return only synchronization status and error codes | Simplifies the receiving logic of external systems, focuses on core validation results |
| Maximum context | First 20 records | Adapts to project-level process record audit scenarios, avoids context overload |
variables | Bind project ID and calibration cycle parameters | Achieves precise association between interface calls and business scenarios |
Three common misconfigurations
- A 401 Unauthorized error is returned when calling the interface to upload fixture drawings. Cause: The
Authorizationparameter is not configured correctly, and an authentication token meeting external system requirements is not included. - A parameter missing error is returned when calling the interface to create a text collection. Cause: The
variablesparameter is not passed correctly, and exclusive business parameters for the current project are not bound. - A connection failure error occurs when connecting to an SSE interface with header authentication. Cause: No authentication header field is added in the interface configuration, causing identity verification to fail.
How to confirm correct configuration
- Call the interface to send a single tooling calibration record, check that the returned status code is 200 and
responseDataincludes the correct synchronization status. - View interface logs, confirm that the
Authorizationparameter is correctly parsed, and there are no authentication failure records. - Send multiple change history documents in batch, verify that no timeout errors occur in the interface and data is fully transferred to the knowledge base.
- Call the interface with the associated project ID, confirm that the returned context only includes process records related to the current project, with no irrelevant data included.
